Are you planning on attending the March for Our Lives demonstration against gun violence or want to learn more about the cause?

We've got some answers for you:

What's this all about?

March for Our Lives is a nationwide protest against gun violence on Saturday. More than 500,000 teens and adults are expected to march in Washington, D.C., and in sister marches across the country. A march at the Iowa State Capitol is being organized by statewide group Progress Iowa.

What about parking?

Other transportation options?

Lyft, the ride-sharing app that came to Des Moines in 2017, is offering free rides to the Capitol for those participating in the march. Minors must be accompanied by an adult to participate.

Here's where Lyft service overlaps with planned demonstrations:

Cedar Rapids

Davenport

Des Moines

Dubuque

Iowa City

Sioux City

Waterloo

From Boone, the "Unity In The Community" group is offering a free HIRTA bus transportation to Des Moines march. Information here.

What if I can't participate?

Marjory Stoneman Douglas High School students are soliciting donations on their GoFundMe page. Half the funds will go toward covering expenses with Saturday's march, and half will support the victims and their families of the Parkland shooting.

In addition, they've created a petition to urge Congress to pass gun reform.

There's also another national school walkout planned for April 20 to remember the 19th anniversary of the Columbine High School shooting.

Should I bring young children?

Experts are advising to consider your individual child, to discuss what they might see or hear as a family and to talk about the issues behind the march.

The Chicago Tribune has put together a helpful article on things to consider.
